I ka hoʻomakaʻana o ka mika i mākaukau,ʻoi aku ka nui o ka hoʻohuiʻana o ka collous ether ether ka nui, akā ua paʻa nui ka hanaʻana i ka hana ma kaʻoihana kapu. Pono ke koho kohoʻana i nā'āpana o nāʻano likeʻole o nāʻano likeʻole, nā hōʻailonaʻokoʻa'ē aʻe, e hoʻohuiʻia nāʻano o nāʻano o ka hana o ka hana o ka hana o ka hana o ka hana i ka hana.
I kēia manawa, he nui nā hale kupapaʻu he nui a me nā pohō i ka wai hou i ka hana, a e hoʻokaʻawale ka wai ma hope o kekahi mau minuke. ʻO ka mālama waiʻana he hana nui o ka huiʻana o ka Mathyl Cent, a he hana ia i ka nui o nā mea hana pihaʻole, he nui i nā noho kuʻina, e nānā i. ʻO nā mea e pili ana i ka hopena o ka wai e pili ana i ka nui o ka mika e hoʻopili ai i ka nui o ka mc
1. Ka manaʻo
ʻO Cellulouse eter kahi polyhetic synthetic i hanaʻia mai loko o ka cellouse kūlohelohe ma o ka hoʻololiʻana o keʻano. ʻO Cellouse EterʻO kahi drivative o ka cellouse kūlohelohe. ʻO ka hanaʻana o ka hana o ka cellouse ethes heʻokoʻa mai nā polyhetic synthetic. ʻO ka mea nui loa o nā mea waiwai nui Ma muli o keʻano o keʻano o keʻano cellulose kūlohelohe,ʻaʻole hiki i ka cellulose keʻano o nā mea ithetificalification. Eia nō naʻe, ma hope o ka mālamaʻana i ka luna lole, ua lilo nā kaula hidold ma waena o nā kaula me nā kaula hoʻohuʻu a me nā kaulahao o ka Godluyl Alkali Vekouk. Loaʻa iā cellulouse eter.
ʻO nā waiwai o nā leka uila e hilinaʻi ana i keʻano, helu helu a me ka hāʻawiʻana i nā koi. ʻO keʻano o ka heluʻana o nā mika e pili ana i keʻano o nā cositinies Wahi a keʻano o nā koina ma ka Chale Molecular, hiki ke hoʻokaʻawaleʻia i ka monotera a huiʻia ee. Hoʻohana pinepine mākou i mc e like me mosether, a me PMC e like me ka eter i huiʻia. ʻO Mathyl Cellulose ether Mc ka huahana ma hope o ka huahana ma hope o ka hui hydroxyl ma keʻano o ka glulouse He huahana i loaʻa ma ka hoʻopiliʻana i kahi'āpana o ka hui hydroxyl ma ke pūʻulu me kahi hui methoy a me kahi'āpana me kahi hui hydroxyproopyl. O ka hōʻike statuctularʻo [c6H7OO2 (OH) 3-MNN (OCH3)
I nā hua'ōlelo o ka hopena, hiki ke hoʻokaʻawaleʻia i loko o ka ion a me ka iotic. ʻO ka wai wai wai-waiʻole e pili ana i ka makemake o keʻano o nā keiki heʻelua o nāʻano heʻelua o nā alkyl a me nā lei a alydlyl. Ua hoʻohana nuiʻiaʻo Ionic cmc i nā hana synthetic, nā paʻi paʻi paʻi a me ka dyeing, meaʻai a me kaʻimiʻana i ka meaʻai. ʻAʻole i hoʻohanaʻo MC, PMC,ʻo Hemc, etc. i hoʻohana nuiʻia, nā mea kanu i kēlā me kēia lā, ka lāʻau lapaʻau
2, ka laweʻana o ka wai o ka celllouse eter
ʻO ka wai o ka wai o ka cellouse ether
ʻO ka hana nui o ka wai-soluble collulow emeroa i ka mikaa nui, he'āpana kaiaulu,ʻo ia ke kumu i ka pilina o ke kau. ʻO ka hopena o ka wai o ka wai o ka'ōpū e hilinaʻi ana i ka wai o ka wai, ke kumu o ka maroaroa, ka wā o ka hale o ka moriki, a me ka wā e koi ai ka wai o ka lepo, a me ka wā o ka hana'āina. ʻO ka wai o ka wai o ka cellouse eter e hele mai ana mai ka pānaʻi a me ka dehydration o ka cellouse eter. Keʻike nei mākou a pau,ʻoiai ke kiʻekiʻe o ka cellouse molecular i loaʻa i kahi nui o nā hui hydrable, no ka mea he kiʻekiʻe o ka crystallinity.
ʻAʻole lawa ka hopena o ka hydarxyl o nā hui hydroxyl e uhi i nā pale hydrogen ikaika a me Van des Wals i waena o nā molecules. No laila, ua nāu wale nō ia akāʻaʻole e hoʻokaʻawale i loko o ka wai. I ka hoʻokomoʻiaʻana o kahi mea i hoʻokomoʻia i loko o ke kaula molena,ʻaʻole wale ka mea i kauʻia i ka kaula hydrogen ma waena o nā kaulahao o nā kaulahao kokoke. ʻO ka mea nui loa,ʻo ka mamao loa,ʻoi aku ka mamao ma waena o nā molekula. Ka mea nui loa. ʻOi aku ka nui o ka hopena o ka lukuʻana i nā bonddrogen Bonds, e lilo i ka Eter Cellouse ma hope o ka hoʻopauʻana i ka pattice ma hope o keʻano o ka celcouble. A puka ana kaʻano o kaʻaha wahine,ʻO keʻano o ka Pookmer o ka Cookmer, aʻo ka wai ma waena o nā kaulahao aʻulaʻula. I ka hopena o ka hopena dehydration, hoʻomaka ka molepula i ka hoʻohuiʻana, e hana ana i kahi hanaʻekolu o ke kikowaenaʻekolu a iʻole. ʻO nā mea e pili ana i ka loaʻaʻana o ka wai o ka wai ma ka viscosity i ka viscosity o ka cell
ʻOi aku ka nui o ka viscosity o ka cellouse eter,ʻoi aku ka maikaʻi o ka hana mālama wai. ʻO Viscosity he mea koʻikoʻi nui o ka hana o mc. I kēia manawa, hoʻohana pono ms i nā hana likeʻole a me nā mea hana e ana i ka viscosity o mc. Haike Roy mau anaʻo Haike Rtovvisko, Hourler, Ubbeloohde a me Brookfield. No ka huahana like,ʻo nā hopena he viscosity e anaʻia e nāʻano likeʻole e like me nāʻano likeʻole, a uaʻokoʻa kekahi. Nolaila, i ka wa nana e ana ana i ke kaha o ka makamaka, e laweia mai ai ma waena o ke ano o ka hoike like, rotor, etc.a
ʻO ka'ōlelo maʻamau,ʻo ke kiʻekiʻe o ka viscosity,ʻoi aku ka maikaʻi o ka wai hou o ka wai. Eia nō naʻe,ʻoi aku ka kiʻekiʻe o ka viscosity a me ka kiʻekiʻe kiʻekiʻe o ka mlecular o mc, ka hopena o keʻano kūpono i ka hopena maikaʻi loa. ʻO ke kiʻekiʻe o ka viscosity,ʻoi aku ka nui o ka hopena i ka hopena ma ka papaʻaina, akāʻaʻole kūpono ia. ʻO ke kiʻekiʻe aʻe o kaʻike maka,ʻoi aku ka nui o kalepa ma ka'āina maloʻo,ʻo ia hoʻi, i ka wā o ka kūkuluʻana i kaʻili a me ka hanohano i ke kuʻikahi. ʻAʻole naʻe he mea kōkua ke hoʻonui i ka ikaika o ka'ōlaoanoa o ka muliwai pono'ī. I ka wā o ke kūkuluʻana,ʻaʻole maopopo ka hana anti-sag. Ma ka mea i kū'ē, ua loaʻa kekahi mau mea haʻahaʻa a me nā haʻahaʻa haʻahaʻa akā hoʻololiʻiaʻo Mithyl Coollulose e hoʻomaikaʻi maikaʻi i ka ikaika o ka'ōpū.
ʻO ka nui o ka nui o ka nui o ka cellouse ethe i hoʻohuiʻia i ka martar,ʻoi aku ka maikaʻi o ka hanaʻana, a me kaʻoi aku kaʻoi aku kaʻoi aku kaʻoi aku kaʻoi aku kaʻoi aku kaʻoi aku.
E pili ana i ka nui o ka wahi,ʻo ka mea kūʻai aku i ka paila,ʻoi aku ka maikaʻi o ka wai. Ma hope o nā'āpana nui o ka Eter Cellouse e hele pū me ka wai, nā pale a me ka paleʻana o ka wai e pale ai i nā molepula wai. I kekahi manawaʻaʻole hiki iā ia ke hoʻokaʻawaleʻia a hoʻopauʻia paha ma hope o ka lōʻihi o ka lōʻihi o ka wā hoʻomaha, e hoʻopili ana i kahi spucculent clousty cloudy. Ua nui ka hopena o ka wai o ka wai o nā cetalse eter
ʻO ka maikaʻi kekahi i kahi papa hana koʻikoʻi nui o MiTyl Cellouse Ether. Ponoʻia ka MC i hoʻohanaʻia no ka maloʻo maloʻo maloʻo e pau i ka pau, me ka haʻahaʻa o ka wai, a me ke kumu nui e like me ka nui o ka'āpana ma mua o 6,0um. Hoʻopili ka maikaʻi i ka pālolo o ka cellouse cellounuse eter. ʻO ka wili o ka MC ka mea maʻamau, a he mea maʻalahi ke kīnāʻole i ka waiʻole me ka haʻahaʻa, akāʻaʻole kūpono ia i ka neʻeʻana o ka palau. I ka maloʻo maloʻo maloʻo, ua weheʻiaʻo mc ma waena o nā mea e like me ka hoʻohuiʻana a me ka filler maikaʻi, a me keʻano he nui ke kāwiliʻana i ka wai. I ka wā e hoʻohuiʻia ai ka mc me ka wai e hoʻopau i ka agglometrarates, he mea paʻakikī loa ia e hoʻokaʻawale a hoʻohemoʻole.
ʻAʻole hikiʻole ke hoʻopau waleʻia ka maikaʻi o ka MC I ka wā e pili ana i kēlā me kēia pālahalaha wai maloʻo i kahi nui, e hoʻemi nuiʻia ka wikiwiki o ka mīkini palder lowded, a e hōʻikeʻia nā pilikia ma muli o nā manawa hemo likeʻole. No ka mea i kālaiʻia me ka papa hana mechanical,ʻoi aku ka uku no ka maikaʻi ma mua o ka manawa pōkole pōkole. ʻO ka maikaʻi o ka MC kekahi i loaʻa kekahi hopena i kona mau wai wai. ʻO ka'ōlelo maʻamau, no ka makemake o MiTyl Cellulouse me ka Viscosity likeʻole, ma lalo o ka nui o ka nui o ka wai.
ʻO ka mālamaʻana o ka wai e pili ana i ka mahana i hoʻohanaʻia i ka mahana, a me ka nui o ka wai o ka materl cetally e emi ai ka hoʻonuiʻana o ka mahana. Eia nō naʻe, ma nā noi waiwai maoli, ua hoʻopili pinepineʻiaʻo Moretar ma nā wahi kiʻekiʻe ma lalo o ka nui o ka lā. ʻO ka emiʻana o ka nui o ka nui o ka nui o ka nui o ka nui o ka manaʻo i keʻano o kaʻike i keʻano o ka hana a me ka paleʻana o ka hana a me ka paleʻana o kaʻoi aku ka hopena o keʻano o nā kumu ma lalo o kēiaʻano.
ʻOiaiʻo Mityll Hydroxythyl Cellulouse Eter Ather i kēia manawa e noʻonoʻo nei i ka hoʻomohalaʻana o ka hanaʻana i ka mahana o ka hana o ka mahana. ʻOiai ka nui o ka nui o ka nui o Middl hydroxythyl e hoʻonuiʻia (keʻano kauwela Ma o kekahi mau lapaʻau kūikawā ma MC, e like me ka hoʻonuiʻana i ke kiʻekiʻe o ka ethedification, etc., hiki ke mālama i ka hopena o ka wai.
